The Parable of the Growing Seed
He also said, “This is what the kingdom of God is like. A man scatters seed on the ground. Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. All by itself the soil produces grain—first the stalk, then the head, then the full kernel in the head. As soon as the grain is ripe, he puts the sickle to it, because the harvest has come.”
The Parable of the Mustard Seed
Again he said, “What shall we say the kingdom of God is like, or what parable shall we use to describe it? It is like a mustard seed, which is the smallest seed you plant in the ground. Yet when planted, it grows and becomes the largest of all garden plants, with such big branches that the birds of the air can perch in its shade.”
With many similar parables Jesus spoke the word to them, as much as they could understand. He did not say anything to them without using a parable. But when he was alone with his own disciples, he explained everything.
Mark 6 v 26-34
Your church or Christian group may seem fairly insignificant. Maybe it's large and flourishing. Or maybe you're one of only a few Christians your age in a cold, half-empty building every Sunday and the "kingdom of God" looks unimpressive to say the least. But Jesus says this is what we should expect — it looks small now (like the mustard seed) but its growth is supernatural — it's down to God, and one day it will be seen by everyone. So look around you for signs of the presence and growth of God's kingdom. It is happening.
